Error Message *deploymentdiagram.tlc when building Multitaskmodel for Speedgoat

Hello together,

Since my model now is to big to run on one core on Speedgoat I tried to run it as a Multitaskmodel using explicit partitioning and allowing tasks to run concurrently.

In the single core version of my model everything worked fine and the build had no error.

Now with multitask, i get the erroer message displayed in the picture.

Does anyone know what causes the error message or what to do to narrow down the problem?

Thank you for your help.
